No. 893,817. Patented Jul 21, 1908.

T0 allcuhom it may concern.- I described forms the subject-matter of a com l3e 1t known that I, ARrHUa W. SMITH, panion application, filed May 15, 1905, Serial citizen of the United. States, and resident of I N o. ,260,441,'andit is therefore notdeemed 1nv the county of New 1 herein. The type ends of the type bars 7 rest nor- Improvements in TypeWVriting Machines, of mally against an ink pad 19 of felt'or mate'- which the following is a specification. I rial of similar My inventionrelates to inking devices for pregnatedwith ink. The ink pad 19 is segtypewriting machines, and has for its main mental in shape, as appears in Fig. '2, and object to provide an improved ink pad case rectangular in cross-section. The pad is conor holder and one which may be readily tained in a segmentaltrough-like case or placed in position in the machine and reholder 20, preferably made of metal and moved therefrom. formed in one piece. The ends of the case 20' To these ends the invention resides in the are provided with laterally extending tabs or ears 21 which rests on the top late 4 and support the pad case in the mac ine.

' As best ap is vertically arranged with its bottomsurface at an angle. to the horizontal. Thefront wall 20 and the bottom 20 of the case are guided and sup orted centrally of the machine by an ang ed metal strip or bracket 22 which is perforated to permit ork and State of New vices and arrangements of fully described in the claims.

Inthe accompanying drawings, Figure 1 is arts hereinafter and particu arly'pointed out p I ears in Fig.'1, the pad case 20 view of so much-of a typewriting machine as invention.

Fig. 2 is a front elevationof the ink pad and the pad case or holder and showsupporting the ends of the 3 is an enlarged fragmentary right angles to the face of the ink pad. Fig. 4 is an enlar ed transverse sectional view of the ink paccase and ink ad. i

In the drawings the main frame of the machine is shown as comprising a. base 1, side portions or plates 2 and a rear end 3. A suitable top plate 4, having forwardly rojecting side portlons 5, is secured to the si e plates 2 and the rear end 3 of the frame.

, A platen. 6, diagrammatically shown, is arranged above the top plate and constructed to be moved from side to side thereof in a known manner during the operation of the machine. A type bar 7 is designed to cooperate with the front face of theplaten 6, said type bar lying normally belowsaid platen and being one of a segmentally arranged setype bar 7 whereof is connected with a guide link 8 and with an actuator or driver 9. The driver 9 is ivoted at 10in a hanger 11 secured by hea ed screws 12 to a segmental support 13 which is suitabl frame of the machine. Eac actuator 9 is connected by. a link 14 with a bell-crank lever 15, which in turn is connected by a link 16' with a key lever 17 pivoted at 18. The type bar, actuatingimechanism just latter. Fi

g screws 12' securing the bracket 22 in place. The bracket 22 is provided at its upper end with arms 22 and 22 which form a crotch in which the pad case is received, the construction being. such that the lower part of edges of the side portions 5 of the top plate are formed V at the rear with recesses or notches as indicated at 5* (Fig. 1) and the upper parts of the pad case are received in these notches so that the ends of thepad. case cannot be displaced fore and aft of the machine. Interposed between the wall 20 of the pad case andthe adjacent 'face of the pad is a regulator or pressure device which, as herein shown, is in the form-of asegmental .follower'or plate 23. The regulator plate or follower-23 conforms substantially in shape to the inner face of the front wall 20 'of the pad case and is adjustable, serving in eflect as a false wall or movable side ofsaid case; The means herein shown, for adjusting the plate-23 are in the form of set screws 24 which 1 are received in threadedopenings in the fixed front wall '20 ofthe ad case and are shouldered off at 25, so ti l are of smaller diameter than the body porthe side portions 5 of isposed in the machine, and is the passage of the screws 12 of the central hanger 11,- said necessary to set it forth in greater detail 7 properties and suitablyimthe pad case is maintained in a fixed position fore and aft of the machine. The inner at-th'eir'inner ends 62 tions of the screws. The ends 26, as bestappears in Fig. 4, are not threaded and are received in perforations in the inner movable wall or plate 23 against the outer face whereof the shouldered, portions 25 of the regulating or adjusting screws; 24 abut. I have shown five regulating screws each controlling the pressure at a different sectional portion of the ink (pad, one screw beingnarranged near each en of the pad, one at about the center,

.and one about midway, between the center 1 screw and each end screw, but, of course, the

that part of the surface whereof is exhausted,

with the result that ink from the interior or other parts of the pad is brought to the desired portion of the surface. In order to remove the pad case it is only necessary to raise all the type bars far enough from the surface of the pad to enable the case to be lifted out--. of the machine. that the pad case is normally maintained in position, embraced centrally by the crotch 1n the bracket '22, and with the tabs or ears 21 resting against the top plate of the ma. chine, by the weight of the ad case itself and that of the type bars, an it is only necessary to lift the ty e bars slightly to enable the ad case to be slipped into or out of the mac ine.

After thepad case has been removed from the machine the regulator plate-or pressure device 23 may be forced in whole or in part towards the rear wall of the pad caseiby screwing in the regulating screws '24:. One or all of the screws may be adjusted at any particular time as desired, according as the has been exhausted from one part or sec tion only of the surface adjacent oneof the screws 24' or uniformly from-the entire surface- As any screw is screwed in that part of the plate or pressure device 23 controlled by it is forced towards the opposite wall of the pad case, thereby compressmg the neighb'oring portion of the pad and forcing the ink in the interior or other part of the pad towards the desired part where said ink is available to supply the types. After regulatingthe inksupply as described, the'pad may be restored to-normaYpositiOnin the operative on the pad to increase the uantypes and increasing to a different extent the tion with t e types, ofan ink pad onwhich 130- machine in the manner above explained.

It'will be seen "that by my invention I provide in combination with an ink pad, means tfizy of ink't'aken therefrom by so'm'e o y of t e t of in ta on from the pad by some of the It will be noted t ratel'y'on the ink in said pad to increase the es or at-will increasing the-quantity quantity taken by' others of the types"; that said means is su ported by thepad case and includes devices or compressing difi'erentportionsof the ad separately and for forcing ink to particu ar selected portions of the face of the pad; that the pad casein the present instance is convexo-concave in form; that the convex side of the case is closed and extends downward from each endof the case;

that the pad hasa concave face on which the types normally rest; and that the construction is such that any excessive ink which may be squeezed out of the pad will be held in the pad case and will not drop down through the machine. 1

Various changes may be'efiected in the construction an arrangements of the parts withinlthe scope of my invention. Q Q
